To @il whom it may ransom:

Be it knovm that 1 Entrants Sierre,

citizen of. the United States, residing et frberdeen, in the countyof Chehelis end tete or Wasnrngton, here invented certain i new and useful improvements in Wrenches,

'o f. which. the following is. a specification,

reference being` had therein to the :wrom- 'pan'ving drewing.

T is invention relates to improvements in Wrenches, end has for its object the improvement oi the construction of wrenches, whioh are Iprovided with e siidsble jew mounted i -upon a shank, which shenh is, preferably,

provided with s fixed jaw. y Another object or" the invention is the peouhar construction of e sliding gaw oi e.

wrench. and the nut, whereby the nut 'pre vente the jaw trom engaging or injuring the threads of the sh ank.

With these end other objects in View, the

., iinventionwonsists oi certain novel construc- Utions, oombinetions, and arrangements of gripping or toothed face 6, whereas in F 1g. 3, v

. tion 3.

parte, as will be herein-exeter hilly described end Claimed.

in the drawings: Figure i is a view in side elevation of the wrenoh, showing the sliding jaw in longitudinal section. Fig. 2 is a view of snor-her embodiment of a. wreneh, lshowing the sliding jew sind the nut in longitudinal section. Fig. 3 is another embodiment of the present invention, showing the sliding' jaw ond the nut in longitudinel seotion. Fig. e is a transverse, seotionel view of the sliding` jaw and the sh ank and showing in dotted lines the nut. Fig. 5 is e pers .ective of the nut. Fig. 6 is an end View o the nut.

Referring to the drawings by numerals, 1v

designates the shank, which is provided with a handleortion 2, and with a threaded poriiitegral with the shank 1 is a stof tionery jaw e; The jaw L1, in Fig. 1, is prrr vided with a smooth, inner face 5, while in 2, the `jew 4 is provided with a pipethe `raw 4 hss two engaging faces, to wit: the flat o r smooth face 5 and the'pipe-gripping face The sliding jaw 7 is provided with e ieee S corresponding; to the' face' whereas the sliding jew 7 is provided with i pipegripping or toothed or roughened :e

responding to face or grip ing-portion 6. in the embodiment depicts in Fig. 3, the slid.-

ingr aw This providedwith a smooth feceA 1()y oorresponding to the face 5'-, and said yew` 1s aiso provided. with e pipe-gripping face or toothedfsurfeoe 9 corresponding to thefsurrece or'iaee 6. lt wiil he obvrousthat the wrench shown in Fig. 3 can be used'uponan ordinary square nut, or uponpipes, on obf jects having a round surface. l 4

in each oin the embodiments, the sliding. gew is provided with inner, parallel walls or faces 1l end with streight, transverse shouljew 'from rattling or 'raving any sidewise;

movement towards the threads on the threaded portion 3 of the shenirl, thereby preventing the sliding jlew from injuring orwearv ing the threads, W lich is of' very great inn pertence, owing to the extension of the life of the 'wrench and the holding of the jaw and the nut in a firm, operative, osit1on It 1.fill he obvious that the oyiindrioal nut 1s in ternelly screw-threaded, as at 15, and is provided witha rou hened or a serrated, outer surface upon the ody, Figs. 1 end 5.

The sliding shank is provided at .both ends with elongated or substantially oblong apertures' 16, through which projects the shank said shank fits oomparativeiy snug Within the apertures 16. While the sliding aw may heI Iadjusted freel upon the threede portion the shsnlr, sti i it is supported et its straight, transverse shoulders 12, 4upon the annuler the nut be provided. with the reduced, en-

nular portions' or reduced oylindrioel exten sions ie at its ends, sov then both ends of the siiding jew may be supported sway from thel shrink st el! times. Furthermore, thepe-n oulieilyconstmoted, str-sight shoulders are important, inasmuch they engage the r rduced portion. oi the nut. and at thesame time permit the disassenihling of the nut 8.5i reduced extensions i4 of thecompare..t-iveiyy.y large cylindrical nut. It 1s importent that from the ,sliding jaw, upon the shenk being removedJ by merely moving said nut sidewise or laterally out of the jaw.

What i. Claim is:

1. A wrench, comprising e, shank, a, sta,- tionary jaw fixed securely to one end of seid shank, seid shank provided near one end with a threaded portion contiguous to said jew, a sliding jaw positioned upon said shank conf tiguous to said threaded portion, said slidii'iggj' jaw provided with a central output v ortion formed by straight, pnrllei, inner wn 1s, said cut-out portion provided at each end with pair of straight, transverse, shoulders, e cylindrical nut positioned Within the out-out portion of said siiding aw and surrounding the threaded portion of said shank, seid nut provided at itsends With Ineens engaging ali of the shoulders and entirely sup ortingsaid sliding jaw away from the three ed portion of the shank.

2. A Wrench, oompsing :t threiided shank', e jaw engaging seid shank at one end, e slid- 1ng-jaw mounted upon the threaded portion of said shank, e rotatable nut positioned Within said s iiding jew and engaging seid threaded oition of the shenl, seid nut pra vided Wit reduced, ennuie? extensions at its end s, Seid ennuisn extensions siidelbiy en inging and snp orting tne sliding jaw away :i

said shrink, said sliding-jew provided with a.

eut-onq position, seid cutout poitioil pio vided with pir o? shoulders eeen endF the snoei their inner faces for allel position, and e, mit within said sliding-jew pro ende with Ineens engaging ell the shoulders `of the sliding for entirejf supporting seid Jaw upon sin( sanne.

In testimony whereof i. hereunto et? my signature in presence of two Witnesses.
